WATER-PURIFYING APPA RATUS.

Specification of Letters Patent.

Application filed October 11, 1906- Serial No. 338,445.

To all whom it may concern.-

Be it known that I, ALBERT E. DIETERICH, residing at IVashington, in the District of Columbia, have invented certain new and useful Improvements in IVater-Purifying Apparatus, of which the following is a specification.

My invention relates to certain new and useful improvements in water-purifying apparatus; and it particularly relates to that class of water-purifying apparatus employing electrolysis for precipitating the impurities in the water and mechanical means for filtering out the precipitated impurities.

In its generic nature my invention has for its object to provide a water-purifying apparatus of a very simple and effective construction, which can be easily and cheaply manufactured, and which will readily and effectively serve its intended purposes, and which is,- furthermore, particularly adapted for household use.

In its more detailed nature my invention comprises a casing having closure-caps at each end, a core of non-conducting material which is waterproof and upon the outside of which a'water-containing groove is formed,

extending, preferably, in a spiral line from the bottom of the casing to a point adjacent the top thereof, the core being hollow to form a water-chamber within which a filtering-stone is suspended, through which the water must pass before it passes out of the discharge-pipe that is in communication with the interior of the filtering-stone. Tithin the water-passage of the core a pair of electrodes are held, and these electrodes have terminals which pass out through one of the closure-caps, by means of which they are connected to a source of electric-current supply.

In its still further detailed nature my invention also comprises certain novel construction, operation, and arrangement of parts, all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure l is a central vertical sectional view of my invention, parts being shown in elevation. Fig. 2 is a view of my invention,

the casing and insulation between the core and the casing being shown in longitudinal section and the core, the surrounding electrodes, and the closure-caps for the casing being shown in side elevation.

Figs. 3, 4,

and 5 are sections, respectively, on the lines I f tion shown in the drawings is of a cylin drical shape and provided on its periphery with a deep spiral groove extending from bottom to top thereof, and Within the bottom of the groove the negative electrode 2 is wound. i

The electrode 2 is in the'nature of a thin strip of sheet-aluminium whose lower end is' bent to form a contact-strip 2*,iiito which the contact 4 is secured. The upper end of the negative electrode 2 has an ear or rivetlike portion 2 whichis bent through an a erture 1 in the core 1, as indicated. T e electrode 2 is preferably tightly'wound into the spiral so that it will lie tightly against the bottom of the spiral groove. Wound preferably in the spiral groove 1 ofthe core 1, but spaced from the electrode 2, is a second electrode 3, which forms the positive electrode and is preferably constructed of a thicker strip-of aluminium than that of the electrode 2, the spiral groove 2 "or channelfl being preferably shaped to receive the strip 3 and hold it in place, so that the outer surface of the strip 3 will preferably lie parallel with the outer surface of the core 1. Thus it will be seen that by reason of the formation of the spiral groove 1" within the core 1 a spiral water-passage is produced from one end of the core to the other and the water is caused to pass between the electrodes 2'and 3. The core 1 is open at its upper end and'has its lower end closed by a bottoml on the bottom surface of which a groove 1 is formed, which communicates with the'inlet from the inlet-pipe 20, and the groove 1 merges with the groove 1 within which the contact 2 is held. The electrode 3 has its lower'end bent into a contact-strip 3*", which lies inthe supplemental groove I in the bottom'of the core 1 and with which the contact-post 7 iS connected. The upper end of the electrode 3 is bent over into an ear 3*, whichliesjin the groove 1 in the top of the core 1. The electrode 3 is preferably tightly woundin the groove 2, so as to form as nearly as practicable a water seal.

Surrounding the core 1 and its electrodes I place an insulating material 17, which may be of any approved material and constructionsuch, for instance, as soft rubberto from a packing, as well as to serve insulation purposes. The core 1 and its insulatingcovering 17 are then placed within a tube to snugly fit the same, and the tube 10 is closed at each end by screw-caps 11 and 12, insulating-washers 15 and 16 being provided for the caps 11 and 12, respectively. The contacts 4 and 7 pass through the cap 12 and are insulated therefrom, as indicated, and receive contact-washers 5 and 8, respectively,

andmilled nuts 6 and 9, respectively. The

intake-pipe communicates with the source of water-supply and is passed through a hublike portion in the cap 12 and communicates with the groove 1 as before stated. The core 1 is hollow to form a water-chamber 1,

with which the aperture 1 at the top of the core communicates, and the cap 11 carries a hollow filter-stone 18, which is cemented or otherwise secured in the cap, as at 18", and the stone 18 is hollow to form a water-chamber 18, from which the water passes out through the spout 19, as indicated by the arrows in Fig. 1, it being understood that the spout 19 is carried by the cap 11 and communicates with the chamber 18 as shown.

From the foregoing description it is thought the complete construction of my invention will be readily understood by those skilled in the art to which the invention ap pertains, and the manner in which my invention operates will be best explained as follows: The pipe 20 being connected to any suitable source of water-supply and the neg ative electrode 4 and the positive electrode 7 being connected, respectively, to the proper terminals of a suitable source of electric energy, the water as it enters the purifier through the pipe 20 is received in the groove 1 and passes through the same and the passage 1 into the spiral channel 1 on the outside of the core 1. I

- In this channel the water passes between the electrodes 2 and 4, where it undergoes the action-of the electric current, and in which channel 'or groove 1 the electric current pre cipitat'es the impurities in the water in a manner well understood by those skilled in the art to which this invention appertains. As the water passes through the groove 1 around the core 1 and reaches the aperture 1 it passes through the aperture 1 and is discharged with all its precipitated impurities into the chamber 1 passing through the filter-stone 18 into the waterchamber 18 thereof. As the water passes through the filter-stone 18 it will be relieved of all the suspended impurities, and when it passes out of the chamber 18 through the spout 19 the water will be perfectly clean.

By reason of the construction of my purifying apparatus the same can be readily taken apart for cleaning purposes, since the water enters at the bottom and passes up toward the top and all impurities will pass along with the water and be discharged into the chamber 1 and be collected on the stone 18 as the water passes therethrough, -and hence to clean my purifier it is only necessary to unscrew the cap 11 and wash the filterstone 18. When the electrode 3 becomes decomposed and it is desired to resupply the electrodes, it is only necessary to unscrew the cap 11, remove the same and the filterstone, unscrew the milled nuts 6 and 9, and pull the core 1 out through the top of the casing 10, after which the old electrodes can be taken off and new ones substituted. This latter operation of changing the electrodes is only occasionally required, as when they become decomposed by electrolysis after long While I have described the invention and specifically referred to the covering 17 as being an insulating and packing material, yet I desire it understood that the insulation 17 may be entirely dispensed with and the casing 10 may be made of an insulating substance, all of which and other slight changes in the detail construction and arrangement of parts may be made without departing from the spirit of the invention or that of the ap pended claims.
